GETTING STARTED WITH AIR INTEGRATION
Follow this guide to install and pair your Shearwater transmitter with your dive computer.
Transmitter Install Procedure:
For Swift and Swift GPS
1. Position the Transmitter on Same Side as your Dive Computer.
Range is approximately 3’ (1m). Angle to side or point slightly forward. For complex installations, a short high-pressure hose may be required.
2. Hand-tighten the Transmitter on HP Port of 1st Stage
Use a 1st stage with two HP ports so that a backup analog SPG can also be installed. Ensure the o-ring is present and free of debris when installing the transmitter. O-ring size is -012 and we recommend Viton® material for replacements.
3. Open Tank Valve
The transmitter will automatically turn on when it detects pressure. Likewise, the transmitter will automatically turn off after 2 minutes of no pressure. Therefore, to turn off the transmitter, close the tank valve and bleed the pressure by purging your 2nd stage. For now, leave the valve open.
4. Enable AI on your Dive Computer
For Perdix 2, Petrel 3, Peregrine TX and NERD 2:
Navigate to the System Setup > AI Setup. Change the AI Mode setting to On.
For Tern TX and Teric:
Navigate to the Settings > AI menu. Change the AI Mode setting to On.
5. Pair the Transmitter
You only needed to set this up once, as it will be permanently saved in the dive computer's settings memory.
Obtain the Serial Number
Each transmitter has a unique serial number etched on its body. All communications are coded with this number so that the source of each pressure reading can be identified.
For Perdix 2, Petrel 3, Peregrine TX and NERD 2:
Pair the transmitter by going to the Tx Setup menu option, and selecting T1. Turn on T1, then enter 6-digit transmitter serial number into the T1 Serial # setting.
For Tern TX and Teric:
Pair the transmitter by going to the Tx Setup menu option, and selecting T1. Turn on T1, then enter 6-digit transmitter serial number into the T1 Serial # setting.
6. Add an AI Display to the Main Screen
The main screen will not show any AI displays until they are added. Alternatively, the AI info can be left off the main screen, and then accessed by navigating to the AI Info screen.
For Perdix 2, Petrel 3, Peregrine TX and NERD 2:
In recreational diving modes, add AI to the home screen in the System Setup > Bottom Row menu.
The center row can be customized extensively to show a variety of information.
For Tern TX and Teric:
In all dive modes, when using the Big layout, the right Info Row slot can customized to show AI information.
In any dive mode, when using the Standard layout, the info row can be customized extensively to show AI information.
Use the Settings > Dive > Home Screen menu to add an AI display to your home screen.
Ready to Dive!
Your tank pressure should now be displayed which means the Air Integration feature is now ready to dive.
If you see a “No Comms” message, ensure the tank valve is turned on and the transmitter-to-computer distance is less than 3 ft (1m).
AI DISPLAYS
Pressure Readings
The current tank pressure is shown in PSI or Bar.
Pressure Icon
The bar graph provides quick visualization of the pressure.
Alerts
Warnings and status may be displayed.
Gas Time Remaining (GTR)
GTR is similar to NDL. GTR is the time, in minutes, that you can remain at the current depth until a direct ascent would result in surfacing with the reserve pressure remaining.
GTR is based on your current SAC (surface air consumption) rate. GTR (and SAC) are not measured while on the surface and not shown for the first few minutes of a dive, until enough data is collected for estimates.
